Recreating the village: the patient experience with a hybrid model of Group Perinatal Care (GPPC) in an academic family health team.

BACKGROUND: Group prenatal care (GPC) has been shown to have a positive impact on social support, patient knowledge and preparedness for birth. We developed an interprofessional hybrid model of care whereby the group perinatal care (GPPC) component was co-facilitated by midwives (MW) and family medicine residents (FMR) and alternating individual visits were provided by family physicians (FP's) within our academic family health team (FHT) In this qualitative study, we sought to explore the impact of this program and how it supports patients through pregnancy and the early newborn period. METHODS: Qualitative study that was conducted using semi-structured telephone interviews with 18 participants who had completed GPPC in the Mount Sinai Academic Family Health Team in Toronto, Canada and delivered between November 2016 and October 2018. Interviews were audio-recorded and transcribed verbatim. Thematic analysis was conducted by team members using grounded theory. RESULTS: Four over-arching themes emerged from the data: (i) Participants highly valued information they received from multiple trusted sources, (ii) Participants felt well cared for by the collaborative and coordinated interprofessional team, (iii) The design of GPPC enabled a shared experience, allowing for increased support of the pregnant person, and (iv) GPPC facilitated a supportive transition into the community which positively impacted participants' emotional well- being. CONCLUSIONS: The four constructs of social support (emotional, informational, instrumental and appraisal) were central to the value that participants found in GPPC. This support from the team of healthcare providers, peers and partners had a positive impact on participants' mental health and helped them face the challenges of their transition to parenthood.

Implementation of Multiple Marker Screening for Preterm Preeclampsia in a Single Tertiary Obstetric Centre.

OBJECTIVES: Early assessment of pregnant individuals for risk of preterm preeclampsia (PE) is possible at the 11-14 week ultrasound visit using a validated multiple marker algorithm, allowing timely use of preventative low-dose acetylsalicylic acid (LDA) in high-risk patients. With no established early screening program for preterm PE in Canada, our objectives were to assess the acceptability and operational impact of routine screening for preterm PE during the 11-14 week ultrasound visit, evaluate uptake and adherence to LDA when recommended, and assess screening performance. METHODS: A prospective implementation study of preterm PE screening among pregnant patients at the ultrasound unit of a tertiary obstetric centre in Toronto, Canada. RESULTS: A total of 1057 patients were screened, with an acceptance rate of 87.1%. First-trimester ultrasound appointment time increased by a median time of 7 minutes (Interquartile range 6-9). By 16 weeks gestation, 88.7% of high-risk patients had started LDA, with adherence of 88.7%‒94.6% from 16‒36 weeks. Satisfaction with counselling was ≥7/10 in more than 95% of patients. There were 7 cases of preterm PE (0.73%), 3 in the low-risk group (0.35%), and 4 in the high-risk group (4.1%). When accounting for LDA use, the treatment-adjusted detection rate was 78.6%. CONCLUSIONS: We demonstrate successful implementation of a validated, effective screening and prevention program for preterm PE as a first step in the implementation of a broader program adaptable for cultural, access/equity considerations, and marker availability.

Do Psychological and Behavioural Factors Change Over Pregnancy?

OBJECTIVES: To investigate how psychological and behavioural factors change from the first to the last half of pregnancy. METHODS: In this prospective cohort study, we assessed the changes in psychological and behavioural factors across 10 domains among 445 women (mean age = 30.9 years) in Ontario, Canada. We collected data using 2 standardized questionnaires administered at <21 and 32-36 weeks of gestation. We computed intraclass correlation coefficients, percentages of no change, decrease, and increase, and mean differences between the 2 surveys. RESULTS: Most psychological and behavioural factors had intraclass correlation coefficients < 0.50 between the first and the second half of pregnancy, suggesting remarkable changes over the course of pregnancy. We observed significant decreases in self-efficacy, compensatory health beliefs, guilt regarding binge eating, emotional eating, dietary restriction, pregnancy-related nausea and food cravings, sleep duration, and physical activity. We also found increases in anxious and depressive symptoms and the tendency to accept friends' and family's beliefs regarding pregnancy. CONCLUSIONS: In the first prospective analysis, we found that many psychological and behavioural factors changed significantly over pregnancy.

Psychological Distress and Behavioural Changes in Pregnant and Postpartum Individuals During the COVID-19 Pandemic.

OBJECTIVES: To determine the psychological and behavioural effects of the COVID-19 pandemic on a Canadian cohort of individuals during pregnancy and the postpartum period. METHODS: In 2020, individuals between 20 weeks gestation and 3 months postpartum receiving maternity care from an urban Canadian clinic were invited to complete a questionnaire. The purpose-built questionnaire used validated scales including the Medical Outcomes Study Social Support Survey (MOS), Depression, Anxiety, and Stress Scale (DASS-21), Edinburgh Postnatal Depression Scale (EPDS), and questions from a SARS study. RESULTS: One hundred nine people completed the questionnaire (response rate, 55%) of whom 57% (n = 62) were postpartum. Most respondents (107, 98%) were married and had completed post-secondary education (104, 95%). Despite these protective factors, moderate to severe levels of depression (22%), anxiety (19%) and stress (27%), were recorded using the DASS-21, and 25% of participants (26) had depression (score ≥11) using the EPDS. Despite high social support in all MOS domains (median scores 84-100), a majority of participants reported loneliness (69, 67%) and were nearly or totally housebound (65, 64%). About half of participants worried about themselves (50, 46.3%) or their baby (59, 54%) contracting COVID-19, while the majority postponed (80, 74.1%) and cancelled (79, 73.2%) prenatal appointments. Being homebound or feeling lonely / lacking support were significant risk factors for psychological distress (P = 0.02) whereas exercise and strong social support were protective (P < 0.05). CONCLUSION: Pregnant and postpartum individuals experienced moderate to severe depression, anxiety, and stress during the COVID-19 pandemic. Exercise and strong social support were protective. Health care provider enquiry of home circumstances and activity may identify individuals needing enhanced supports.

Adapting obstetric and neonatal services during the COVID-19 pandemic: a scoping review.

BACKGROUND: The provision of care to pregnant persons and neonates must continue through pandemics. To maintain quality of care, while minimizing physical contact during the Severe Acute Respiratory Syndrome-related Coronavirus-2 (SARS-CoV2) pandemic, hospitals and international organizations issued recommendations on maternity and neonatal care delivery and restructuring of clinical and academic services. Early in the pandemic, recommendations relied on expert opinion, and offered a one-size-fits-all set of guidelines. Our aim was to examine these recommendations and provide the rationale and context to guide clinicians, administrators, educators, and researchers, on how to adapt maternity and neonatal services during the pandemic, regardless of jurisdiction. METHOD: Our initial database search used Medical subject headings and free-text search terms related to coronavirus infections, pregnancy and neonatology, and summarized relevant recommendations from international society guidelines. Subsequent targeted searches to December 30, 2020, included relevant publications in general medical and obstetric journals, and updated society recommendations. RESULTS: We identified 846 titles and abstracts, of which 105 English-language publications fulfilled eligibility criteria and were included in our study. A multidisciplinary team representing clinicians from various disciplines, academics, administrators and training program directors critically appraised the literature to collate recommendations by multiple jurisdictions, including a quaternary care Canadian hospital, to provide context and rationale for viable options. INTERPRETATION: There are different schools of thought regarding effective practices in obstetric and neonatal services. Our critical review presents the rationale to effectively modify services, based on the phase of the pandemic, the prevalence of infection in the population, and resource availability.

Maternal-Newborn Health System Changes and Outcomes in Ontario, Canada, During Wave 1 of the COVID-19 Pandemic-A Retrospective Study.

OBJECTIVE: To determine the population-level impact of COVID-19 pandemic-related obstetric practice changes on maternal and newborn outcomes. METHODS: Segmented regression analysis examined changes that occurred 240 weeks pre-pandemic through the first 32 weeks of the pandemic using data from Ontario's Better Outcomes Registry & Network. Outcomes included birth location, length of stay, labour analgesia, mode of delivery, preterm birth, and stillbirth. Immediate and gradual effects were modelled with terms representing changes in intercepts and slopes, corresponding to the start of the pandemic. RESULTS: There were 799 893 eligible pregnant individuals included in the analysis; 705 767 delivered in the pre-pandemic period and 94 126 during the pandemic wave 1 period. Significant immediate decreases were observed for hospital births (relative risk [RR] 0.99; 95% CI 0.98-0.99), length of stay (median change -3.29 h; 95% CI -3.81 to -2.77), use of nitrous oxide (RR 0.11; 95% CI 0.09-0.13) and general anesthesia (RR 0.69; 95% CI 0.58- 0.81), and trial of labour after cesarean (RR 0.89; 95% CI 0.83-0.96). Conversely, there were significant immediate increases in home births (RR 1.35; 95% CI 1.21-1.51), and use of epidural (RR 1.02; 95% CI 1.01-1.04) and regional anesthesia (RR 1.01; 95% CI 1.01-1.02). There were no significant immediate changes for any other outcomes, including preterm birth (RR 0.99; 95% CI 0.93-1.05) and stillbirth (RR 1.11; 95% CI 0.87-1.42). CONCLUSION: Provincial health system changes implemented at the start of the pandemic resulted in immediate clinical practice changes but not insignificant increases in adverse outcomes.

Trends and characteristics of Tdap vaccination during pregnancy in Ontario, Canada: a retrospective cohort study.

BACKGROUND: In February 2018, Canada's National Advisory Committee on Immunization (NACI) recommended tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) vaccination during pregnancy to protect newborns against pertussis infection. We sought to describe pre- and postrecommendation trends in Tdap vaccination coverage among pregnant Ontario residents. METHODS: Using linked health administrative databases, we conducted a population-based retrospective cohort study of all pregnant individuals who gave birth in Ontario hospitals between April 2012 and March 2020. We described Tdap vaccination patterns in pregnancy for the entire study period and before and after the NACI recommendation. We used log-binomial regression to identify characteristics associated with Tdap vaccination during pregnancy. RESULTS: Among the 991 850 deliveries included, 7.0% of pregnant individuals received the Tdap vaccination during pregnancy. Vaccine coverage increased from 0.4% in 2011/12 to 29.2% in 2019/20. Coverage was highest among individuals who were older, had no previous live births, had adequate prenatal care and received maternity care primarily from a family physician. After adjustment, characteristics associated with lower coverage included younger maternal age, having a multiple birth, residing in a rural location and higher area material deprivation. In 2019/20, 71.0% of vaccinated individuals received the Tdap vaccination during the recommended gestational window (27-32 wk). Stratified analyses of the pre- and postrecommendation cohorts yielded similar findings to the main analyses with a few gradient differences after adjustment. INTERPRETATION: During pregnancy, Tdap vaccination coverage increased substantially in Ontario between 2011/12 and 2019/20, most notably after recommendations for universal Tdap vaccination during pregnancy began in Canada. To further improve vaccine coverage in the obstetric setting, public health strategies should consider tailoring their programs to reach subpopulations with lower vaccine coverage.

A goal set too high: factors associated with planning excess gestational weight gain in a prospective cohort study.

OBJECTIVE: This study aimed to understand physical, knowledge, psychological, and lifestyle factors associated with planned excess gestational weight gain (GWG), a strong and potentially modifiable predictor of actual excess GWG, which contributes to maternal and child obesity along with other adverse maternal and fetal outcomes. METHODS: This is a secondary analysis of data from a prospective cohort study where women completed a questionnaire in early pregnancy. Women were asked to report their planned GWG, which was then categorized as above, within, or below the Institute of Medicine (IOM) guidelines. Univariable and multivariable analyses were performed to identify variables associated with planned excess GWG. RESULTS: Of 970 women included in the analysis, 300 reported a planned GWG above the IOM guidelines. Predictors of excess planned GWG included reporting healthcare provider recommendations to gain weight above the guidelines (adjusted odds ratio [aOR], 62.17; 95% confidence interval [CI], 13.75-281.03), overestimating first trimester weight gain recommendations (aOR, 1.83; 95% CI, 1.21-2.77), believing in risks to the baby with inadequate GWG (aOR 2.16; 95% CI,1.29-3.60), inaccurate self-perceived prepregnancy body size (aOR, 1.88; 95% CI, 1.22-2.89), low or high emotional suppression (aOR, 1.78; 95% CI, 1.06-2.99; and aOR, 2.57; 95% CI, 1.21-5.45, respectively), physical inactivity (aOR, 1.10; 95% CI, 1.03-1.17), and overweight or obesity (aOR, 5.76; 95% CI, 3.70-8.98; and aOR, 11.46; 95% CI, 6.54-20.06, respectively). Protective factors against planned excess GWG included increased maternal age (aOR, 0.95; 95% CI, 0.92-0.99), and believing in risks to themselves with inadequate GWG (aOR 0.64; 95% CI, 0.42-0.97) or believing in risks to the baby with excess GWG (aOR, 0.49; 95% CI, 0.27-0.88). CONCLUSIONS: Women with overweight or obesity are at greater risk of prospectively planning excess GWG, and may especially benefit from healthcare provider counseling on appropriate GWG. Other modifiable factors for planned excess GWG included knowledge about risks of inappropriate weight gain and physical inactivity.

Obstetric and perinatal health outcomes after pertussis vaccination during pregnancy in Ontario, Canada: a retrospective cohort study.

BACKGROUND: In February 2018, Canada's National Advisory Committee on Immunization recommended maternal vaccination with tetanus-diphtheria-acellular pertussis (Tdap) vaccine during pregnancy to prevent severe pertussis infection in young infants. This study assessed the relation between maternal Tdap vaccination and obstetric and perinatal outcomes in Ontario. METHODS: We performed a population-based cohort study of all births from April 2012 to March 2017 using multiple linked health administrative databases. We used Cox regression with a time-dependent exposure variable to estimate adjusted hazard ratios (HRs) for preterm birth (< 37 wk), very preterm birth (< 32 wk) and stillbirth. We assessed remaining outcomes (gestational hypertension, chorioamnionitis, postpartum hemorrhage, severe postpartum hemorrhage, being small for gestational age, neonatal intensive care unit stay > 24 h, composite neonatal morbidity) using log-binomial regression to generate adjusted risk ratios (RRs). We adjusted estimates for potential confounding using propensity score weighting. RESULTS: Of 615 213 infants (live births and stillbirths), 11 519 were exposed to Tdap vaccination in utero. There was no increased risk for preterm birth (adjusted HR 0.98, 95% confidence interval [CI] 0.91-1.06), very preterm birth (adjusted HR 1.10, 95% CI 0.86-1.41), stillbirth (adjusted HR 1.15, 95% CI 0.82-1.60) or being small for gestational age (adjusted RR 0.96, 95% CI 0.90-1.02). The risks of a neonatal intensive care unit stay exceeding 24 hours (adjusted RR 0.82, 95% CI 0.76-0.88) and neonatal morbidity (adjusted RR 0.81, 95% CI 0.75-0.87) were decreased. There was no association with chorioamnionitis (adjusted RR 1.17, 95% CI 0.99-1.39), postpartum hemorrhage (adjusted RR 1.01, 95% CI 0.91-1.13) or severe postpartum hemorrhage (adjusted RR 0.79, 95% CI 0.55-1.13), but we observed a reduced risk of gestational hypertension (adjusted RR 0.87, 95% CI 0.78-0.96). INTERPRETATION: Our results complement evidence that maternal Tdap vaccination is not associated with adverse outcomes in mothers or infants. Ongoing evaluation in Canada is needed as maternal Tdap vaccination coverage increases in coming years.

Health Outcomes in Young Children Following Pertussis Vaccination During Pregnancy.

BACKGROUND AND OBJECTIVES: Maternal immunization with tetanus, diphtheria, and acellular pertussis vaccine (Tdap) is routinely recommended in many countries as a strategy to protect young infants against severe pertussis infection; few studies have assessed whether prenatal exposure to the vaccine is associated with any longer-term adverse health effects in children. We evaluated the long-term safety of exposure to Tdap vaccination during pregnancy. METHODS: Population-based retrospective cohort study conducted in Ontario, Canada using multiple linked province-wide health administrative databases. All live births between April 2012 and March 2017 were included, and children were followed for up to 6 years to ascertain study outcomes. Children exposed to prenatal Tdap were propensity score matched to unexposed children at a 1:5 ratio. Tdap vaccination during pregnancy was ascertained by using vaccine-specific fee codes. Immune-related (infectious diseases, asthma) and nonimmune-related (neoplasm, sensory disorders) outcomes and a nonspecific morbidity outcome (urgent or inpatient health service use) were evaluated from birth to end of follow-up. RESULTS: Of 625 643 live births, 12 045 (1.9%) were exposed to Tdap in utero. There were no significant increased risks of adverse childhood outcomes and prenatal Tdap exposure; however, we observed inverse associations (adjusted incidence rate ratio [95% confidence interval]) with upper respiratory infections (0.94 [0.90-0.99]), gastrointestinal infections (0.85 [0.79-0.91]), and urgent and inpatient health service use (0.93 [0.91-0.96]). CONCLUSIONS: Exposure to Tdap vaccination in pregnancy was not associated with any increased risk of adverse health outcomes in early childhood, supporting the long-term safety of Tdap administration in pregnancy.

Predictors of Gestational Weight Gain Examined As a Continuous Outcome: A Prospective Analysis.

Background: Excess gestational weight gain (GWG) is common and adversely affects both mothers and offspring, including increasing the risk of maternal and childhood obesity. GWG is typically examined categorically, with women grouped into categories of those who gain above, within, and below guideline recommendations. Examining GWG as a continuous variable, rather than categorically, allows for a consideration of GWG at a finer level of detail, increasing precision. Methods: We collected exposure data among 970 pregnant women in early gestation using a standardized questionnaire in Ontario, Canada, from 2015 to 2017. Maternal weight and height were extracted from antenatal records. Continuous GWG was calculated using four methods: percentage of ideal weight gain, excess GWG, GWG adequacy ratio, and GWG z-score. We used the stepwise linear regression analyses to select variables associated with GWG. Results: We found that a common set of variables (parity, prepregnancy body mass index, planned pregnancy weight gain, smoking, pregnancy-related food cravings, and fast food intake) significantly predicted GWG in a manner consistent across the four GWG outcomes. Certain psychological factors, including the perception of families' and friends' attitudes toward the food cravings of pregnant women, emotion suppression, compensatory health beliefs coupled with eating unhealthy foods, frequent prepregnancy dietary restraint in carbohydrates, sugar, and meals, preferred prepregnancy body size image, agreeable and conscientious personalities, and depression, also were related with GWG. Conclusions: Our findings demonstrate that psychological factors play an important role in the magnitude of GWG, providing key avenues to inform interventions to support healthy weight gain in pregnancy.

Gestational weight gain outside the 2009 Institute of Medicine recommendations: novel psychological and behavioural factors associated with inadequate or excess weight gain in a prospective cohort study.

BACKGROUND: Previous studies have noted traditional physical, demographic, and obstetrical predictors of inadequate or excess gestational weight gain, but the roles of psychological and behavioral factors are not well established. Few interventions targeting traditional factors of gestational weight gain have been successful, necessitating exploration of new domains. The objective of this study was to identify novel psychological and behavioral factors, along with physical, demographic, and obstetrical factors, associated with gestational weight gain that is discordant with the 2009 Institute of Medicine guidelines (inadequate or excess gain). METHODS: We recruited English-speaking women with a live singleton fetus at 8 to 20 weeks of gestation who received antenatal care from 12 obstetrical, family medicine, and midwifery clinics. A questionnaire was used to collect information related to demographic, physical, obstetrical, psychological, and behavioural factors anticipated to be related to weight gain. The association between these factors and total gestational weight gain, classified as inadequate, appropriate, and excess, was examined using stepwise multinomial logistic regression. RESULTS: Our study population comprised 970 women whose baseline data were obtained at a mean of 14.8 weeks of gestation ±3.4 weeks (standard deviation). Inadequate gestational weight gain was associated with obesity, planned gestational weight gain (below the guidelines or not reported), anxiety, and eating sensibly when with others but overeating when alone, while protective factors were frequent pregnancy-related food cravings and preferring an overweight or obese body size image. Excess gestational weight gain was associated with pre-pregnancy overweight or obese body mass index, planned gestational weight gain (above guidelines), frequent eating in front of a screen, and eating sensibly when with others but overeating when alone, while a protective factor was being underweight pre-pregnancy. CONCLUSIONS: In addition to commonly studied predictors, this study identified psychological and behavioral factors associated with inadequate or excess gestational weight gain. Factors common to both inadequate and excessive gestational weight gain were also identified, emphasizing the multidimensional nature of the contributors to guideline-discordant weight gain.

Pregnant during the COVID-19 pandemic: an exploration of patients' lived experiences.

BACKGROUND: Infectious outbreaks are known to cause fear and panic. Exploration of pregnant individuals' psychosocial condition using a qualitative lens during an infectious outbreak is limited. In this study we explore pregnant individuals' lived experiences as well as their psychological and behavioural responses during COVID-19 with the goal of providing useful strategies from the patient's perspective to enable health care providers to help pregnant patients navigate this and future pandemics. METHODS: Pregnant individuals between 20-weeks gestation and 3 months postpartum who received maternity care from an urban academic interprofessional teaching unit in Toronto, Canada were invited to participate. Semi-structured 60 min interviews were audio-recorded, transcribed and analyzed using descriptive thematic analysis. Interview questions probed psychological responses to the pandemic, behavioural and lifestyle changes, strategies to mitigate distress while pregnant during COVID-19 and advice for other patients and the healthcare team. RESULTS: There were 12 participants, mean age 35 years (range 30-43 years), all 1 to 6 months postpartum. Six main themes emerged: 1) Childbearing-related challenges to everyday life; 2) Increased worry, uncertainty and fear; 3) Pervasive sense of loss; 4) Challenges accessing care; 5) Strategies for coping with pandemic stress; 6) Reflections and advice to other pregnant people and health care professionals. Pregnant individuals described lack of social support due to COVID-19 pandemic restrictions and a profound sense of loss of what they thought their pregnancy and postpartum period should have been. Advice to healthcare providers included providing mental health support, clear and up to date communication as well as more postpartum and breastfeeding support. CONCLUSIONS: These participants described experiencing psychosocial distress during their pregnancies and postpartum. In a stressful situation such as a global pandemic, health care providers need to play a pivotal role to ensure pregnant individuals feel supported and receive consistent care throughout the pregnancy and postpartum period. The health care provider should ensure that mental health concerns are addressed and provide postpartum and breastfeeding support. Without addressing this need for support, parental mental health, relationships, parent-infant bonding, and infant development may be negatively impacted.

Does Excess First- or Second-Trimester Weight Gain Predict Excess Total Gestational Weight Gain? A Multicentre Prospective Cohort Study.

OBJECTIVES: Early excess gestational weight gain (GWG) has been examined as a predictor of total excess GWG in a few international studies; however, Canadian data are lacking. We sought to determine whether early (first- and second-trimester) excess GWG predicted total excess GWG. METHODS: We conducted an a priori planned secondary analysis of a multicentre prospective study of English-speaking Ontario women with a singleton pregnancy between 80 and 206 weeks gestation. Our primary outcome was prediction of total excess GWG. We calculated the sensitivity, specificity, predictive values, and likelihood ratios, by body mass index (BMI), for excess first- and second-trimester GWG. RESULTS: Of the 970 women who met the inclusion criteria, 387 and 754, had first- and second-trimester weights recorded in their antenatal record, respectively. For normal, overweight, and obese women, the sensitivity of excess first-trimester GWG for total excess gain was 66%, 68%, and 65%, respectively; and the specificity was 48%, 43%, and 36%, respectively. The sensitivity of excess second-trimester GWG for total excess gain for normal weight, overweight, and obese women was higher, at 92%, 96%, and 95%, respectively; while the specificity was low at 31%, 16%, and 29%, respectively. CONCLUSION: In the first known Canadian study of early excess weight gain as the predictor of total GWG, we found that excess first-trimester GWG did not predict total excess GWG, but that the sensitivity of excess second-trimester GWG for excess total GWG was high across BMI categories.

Competing priorities: a qualitative study of how women make and enact decisions about weight gain in pregnancy.

BACKGROUND: Despite ample clinical evidence that gaining excess weight in pregnancy results in negative health outcomes for women and infants, more than half of women in Western industrialized nations gain in excess of national guidelines. The influence of socio-demographic factors and weight gain is well-established but not causal; the influence of psychological factors may explain some of this variation. METHODS: This is the qualitative portion of an explanatory sequential mixed-methods study designed to identify predictive psychological factors of excess gestational weight gain (QUAN) and then explain the relevance of those factors (qual). For this portion of the study, we used a qualitative descriptive approach to elicit 39 pregnant women's perspectives of gestational weight gain, specifically inquiring about factors determined as relevant to excess gestational weight gain by our previous predictive study. Women were interviewed in the latter half of their third trimester. Data were analyzed using a combination of unconstrained deductive content analysis to describe the findings relevant to the predictive factors and a staged inductive content analytic approach to examine the data without a focus on the predictive factors. RESULTS: Very few participants consistently made deliberate choices relevant to weight gain; most behaviour relevant to weight gain happened with in-the-moment decisions. These in-the-moment decisions were influenced by priorities, hunger, a consideration of the consequence of the decision, and accommodation of pregnancy-related discomfort. They were informed by the foundational information a woman had available to her, including previous experience and interactions with health care providers. The foundational information women used to make these decisions was often incomplete. While women were aware of the guidelines related to gestational weight gain, they consistently mis-applied them due to incorrect understanding of their own BMI. Only one woman was aware that weight gain was linked to maternal and infant health outcomes. CONCLUSIONS: There is an important role for prenatal providers to provide the foundational information to positively influence in-the-moment decisions. Understanding how weight gain guidelines apply to one's own pre-pregnancy BMI and comprehending the well-established link between gestational weight gain and health outcomes may help women prioritize healthy weight gain amongst many competing factors.

Factors obstetricians, family physicians and midwives consider when counselling women about a trial of labour after caesarean and planned repeat caesarean: a qualitative descriptive study.

BACKGROUND: Repeat caesarean sections (CSs) are major contributors to the high rate of CS in Canada and globally. Women's decisions to have a planned repeat CS (PRCS) or a trial of labour after CS (TOLAC) are influenced by their maternity care providers. This study explored factors maternity care providers consider when counselling pregnant women with a previous CS, eligible for a TOLAC, about delivery method. METHODS: A qualitative descriptive design was implemented. Semi-structured, one-to-one in-depth telephone interviews were conducted with 39 maternity care providers in Ontario, Canada. Participants were recruited at 2 maternity care conferences and with the use of snowball sampling. Interviews were audio recorded and transcribed verbatim. Data were uploaded into the data management software, NVIVO 10.0 and analyzed using qualitative content analysis. RESULTS: Participants consisted of 12 obstetricians, 13 family physicians and 14 midwives. Emergent themes, reflecting the factors maternity care providers considered when counselling on mode of delivery, were organized under the categories clinical/patient factors, health system factors and provider preferences. Maternity care providers considered clinical/patient factors, including women's choice … with conditions, their assessment of women's chances of a successful TOLAC, their perception of women's risk tolerance, women's preferred delivery method, and their perception of women's beliefs and attitudes about childbirth. Additionally, providers considered health system factors which included colleague support for TOLAC and time needed to mount an emergency CS. Finally, provider factors emerged as considerations when counselling. They included provider preference for PRCS or TOLAC, provider scope of practice, financial incentives and convenience related to PRCS, past experiences with TOLAC and PRCS and providers' perspectives on risk of TOLAC. CONCLUSION: The findings highlight the multiplicity of factors maternity care providers consider when counselling women. Effectively addressing clinical, health care system and personal factors that influence counselling may help decrease non-medically indicated PRCS.

Prediction of excess pregnancy weight gain using psychological, physical, and social predictors: A validated model in a prospective cohort study.

OBJECTIVE: To develop and validate a prediction model for excess pregnancy weight gain using early pregnancy factors. DESIGN: Prospective cohort study. SETTING: We recruited from 12 obstetrical, family medicine, and midwifery centers in Ontario, Canada. PARTICIPANTS: We recruited English-speaking women with singleton pregnancies between 8+0-20+6 weeks. Of 1296 women approached, 1050 were recruited (81%). Of those, 970 women had complete data (970/1050, 92%) and were recruited at a mean of 14.8 weeks. PRIMARY OUTCOME MEASURE: We collected data on psychological, physical, and social factors and used stepwise logistic regression analysis to develop a multivariable model predicting our primary outcome of excess pregnancy weight gain, with random selection of 2/3 of women for training data and 1/3 for testing data. RESULTS: Nine variables were included in the final model to predict excess pregnancy weight gain. These included nulliparity, being overweight, planning excessive gain, eating in front of a screen, low self-efficacy regarding pregnancy weight gain, thinking family or friends believe pregnant women should eat twice as much as before pregnancy, being agreeable, and having emotion control difficulties. Training and testing data yielded areas under the receiver operating characteristic curve of 0.76 (95% confidence interval, 0.72 to 0.80) and 0.62 (95% confidence interval 0.56 to 0.68), respectively. CONCLUSIONS: In this first validated prediction model in early pregnancy, we found that nine psychological, physical, and social factors moderately predicted excess pregnancy weight gain in the final model. This research highlights the importance of several predictors, including relatively easily modifiable ones such as appropriate weight gain plans and mindfulness during eating, and lays an important methodological foundation for other future prediction models.

Adversity in childhood and depression in pregnancy.

Adverse childhood experiences (ACEs) have been found to be associated with various health conditions; however, there is dearth of evidence on the relationship between ACEs and prenatal depression. This study was conducted to determine the association between overall ACE score and prenatal depression symptoms, assess the moderating effect of social support and partner support on this relationship, and determine the association between individual ACE scores and prenatal depression. A secondary analysis was conducted of data from an RCT that assessed the feasibility of e-screening for maternal mental health among 636 pregnant women recruited from antenatal clinics. Two logistic regression models were built to reach our objectives. Over 80% of the participants were older than 25 years and had education beyond high school. Eighteen percent of the women had an ACE score of four or more. Univariable analysis found a 2.5-fold increase in the odds of prenatal depression for women with an ACEs score of ≥ 4. When examining the overall ACE score, lack of social support during pregnancy [AOR = 4.16; 95%CI (2.10-10.35)] and partner's relationship [AOR = 2.23; 95%CI (1.12-4.44)] were associated with prenatal depression while among the individual ACE scores, living with a person who went to prison was found to be associated with prenatal depression even when controlled for all variables. No moderating effect was found. These findings suggest for the improvement of partner's relationship and provision of social support before women conceive, in order to mitigate the effect of these adversities.

Enhanced skills training in family medicine maternity care: Cross-sectional study of graduates' experiences.

OBJECTIVE: To describe the experiences of participants in Canadian family medicine maternity care enhanced skills programs: their current practice situation with respect to maternity care; the reasons they pursued enhanced maternity care training; and their perceptions of competencies attained during the program. DESIGN: Cross-sectional questionnaire. SETTING: Canada. PARTICIPANTS: Graduates of family medicine enhanced skills programs in maternity care in Canada between 2004 and 2014. MAIN OUTCOME MEASURES: Participants' current engagement in intrapartum care; reasons for participating in the enhanced skills programs; interest in obstetrics at different points in training; and development of maternity care competencies during both core residency and the enhanced skills program. RESULTS: Eighty-seven graduates (response rate of 44%) participated. At an average of 5 years in practice, 77% of enhanced skills graduates were providing intrapartum care. Sixty-nine percent of respondents took the enhanced skills program because they did not feel ready to practise obstetrics without supervision. More than half (55%) of respondents had intended to include obstetrics in their future practices when they were in medical school. By the end of residency, 99% intended to practise obstetrics; however, this percentage decreased to 87% by the end of fellowship. There was a statistically significant increase in graduates' perceptions of various maternity care competencies (eg, vacuum-assisted birth, perineal repair) following enhanced skills training. Eighty-two percent of respondents indicated that the ability to access enhanced skills training supported their decision to provide obstetrics care. CONCLUSION: This is the first evaluation of graduates of enhanced skills programs in maternity care in Canada. Enhanced skills programs appear to support the education of family medicine maternity care providers; however, these programs might be compensating for residents' lack of confidence in providing maternity care independently rather than providing truly enhanced skills. This study also confirms that some medical students and family medicine residents change their minds in the direction of wanting to provide full-scope maternity care during the course of their education.

What influences success in family medicine maternity care education programs? Qualitative exploration.

OBJECTIVE: To ascertain how program leaders in family medicine characterize success in family medicine maternity care education and determine which factors influence the success of training programs. DESIGN: Qualitative research using semistructured telephone interviews. SETTING: Purposive sample of 6 family medicine programs from 5 Canadian provinces. PARTICIPANTS: Eighteen departmental leaders and program directors. METHODS: Semistructured telephone interviews were conducted with program leaders in family medicine maternity care. Departmental leaders identified maternity care programs deemed to be "successful." Interviews were audiorecorded and transcribed verbatim. Team members conducted thematic analysis. MAIN FINDINGS: Participants considered their education programs to be successful in family medicine maternity care if residents achieved competency in intrapartum care, if graduates planned to include intrapartum care in their practices, and if their education programs were able to recruit and retain family medicine maternity care faculty. Five key factors were deemed to be critical to a program's success in family medicine maternity care: adequate clinical exposure, the presence of strong family medicine role models, a family medicine-friendly hospital environment, support for the education program from multiple sources, and a dedicated and supportive community of family medicine maternity care providers. CONCLUSION: Training programs wishing to achieve greater success in family medicine maternity care education should employ a multifaceted strategy that considers all 5 of the interdependent factors uncovered in our research. By paying particular attention to the informal processes that connect these factors, program leaders can preserve the possibility that family medicine residents will graduate with the competence and confidence to practise full-scope maternity care.
